Answer:
The sample contains protein.
Explanation:
Biuret test is a test used to determine or assay for proteins in a solution. When the biuret reagent is added to a solution and it turns blue after 2 minutes, it means that the solution contains protein.
Benedict’s test is used to determine the presence of sugar (reducing sugar) in a solution. When it turns brick red, it means there is the presence of reducing sugar in large quantity.
From the question, since the solution turned blue on addition of Biuret reagent and was also blue on addition of Benedict’s reagent (the reagent is usually blue), it means that the solution contained just proteins excluding reducing sugars.
Answer:
internal validity; external validity
Explanation:
The simulation experiment or a computer experiment is performed to verify the correctness of any program or operation and to evaluate the performance of the proposed project.
It is mainly used for the process analysis as well as for the process optimization of the experiment. Doing a simulation experiment maintains the internal validity of the experiment. It also maintains the external validity of the research that is conducted in the real world.
